Pool Heater Energy Usage

What is a Pool Heater?

Few things can match diving into a cool, refreshing pool on a hot summer day. However, there might be too much cold. The pool water doesn't need to be too cold to feel refreshed. 

To solve this one, we have pool heaters. Pool heaters can add a little warmth to make the pool a fun and inviting place to hang out on chilly summer afternoons

A pool heater removes pool water and transfers it to a heating tank, where it is heated before being returned to the pool. Even when it's freezing outside, your pool will remain at a pleasant temperature thanks to this exchange of cold and warm water. If you are unfamiliar with pool heaters, there are some essential things to know.

Electric and gas pool heaters are the two varieties that are available in the market right now. But if you are using or have an electric pool heater, you would want to know how much energy is consumed by your electric pool heater or how much wattage or the kilowatt per hour it consumes. 

The electric pool heater, also referred to as the heat pump, is the earliest type of pool heater. A heat pump draws air from outside your pool using a fan; it is the more environmentally friendly of the two. 

The pump then circulates the sun-heated air through an air evaporator coil. After that, the air transforms into a warm gas that condenses into an even hotter gas, warming the pool's chilly water. Water enters cold and leaves warm. 

Types of Pool Heaters

Pool heaters using propane 

A propane heater burns one gallon of fuel every killowatt hour for every 100,000 BTUs. That equates to 4 gallons per hour for a heater of a typical size with 400,000 BTU.

Pool Heaters Using Natural Gas

NG heaters, commonly known as natural gas, utilize approximately one therm per hour for every 100,000 BTUs. This is equivalent to 4 therms per hour for an average size 400,000 BTU pool heater.

Heat Pumps

‍For every 100,000 BTUs, heat pumps will consume about 5,000 watts or 5 kilowatts per hour. 

That is 5 kilowatts per hour for a heat pump of a standard size of 100,000 BTU.

Wattage Use of Pool Heaters

There are approximately 5 kilowatts per hour, each heat pump with 100,000 BTU. You'll use about 5,000 Watts per hour of power for a typical 100,000 BTU pool heat pump.

So, are pool heat pumps expensive to operate? Despite costing somewhat more than gas pool heaters, they typically have lower yearly operating costs because of their higher efficiency. These pool heaters will last longer than gas pool heaters if adequately maintained. As a result, you will eventually save a lot more money.

For example, a heat pump will cost—eighty cents for an hour. With no solar cover, you may typically expect 1 to 1.5 degrees of temperature change per hour to heat an ordinary pool (10–12K gallons).

Please be aware that heating durations will lengthen if your water is colder than usual.

How much wattage consumption is added to your electricity bill with pool heaters?

A pool heat pump will increase your annual electricity cost by roughly $300. You can leave it on constantly because it is not that too expensive. 

Again, considering that the heat pump changes the warm air in the area and sends it to your pool, this might be an excellent option. It would help if you thought about solely using it throughout the day to maximize energy efficiency. 

However, it would be preferable to run it all night if you want to swim in the morning and need the water to be warm.
